HMC253LC4

HMC253LC4 v00.0107 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Typical Applications The HMC253LC4 is ideal for: • Basestations & Repeaters • WiMAX/WiBro & Fixed Wireless • Cellular/3G Infrastructure • CATV/DBS • Military & Hi-Rel Features Ceramic, RoHS Compliant 4x4mm SMT Package Non-Reflective Topology Low Insertion Loss: 1.2 dB Single Positive Supply: Vdd = +5V Integrated 3:8 TTL/CMOS Decoder: 0/+3V 9 SWITCHES - SMT Functional Diagram General Description The HMC253LC4 is a non-reflective SP8T switch in a leadless RoHS compliant 4x4 mm ceramic SMT package featuring wideband operation from DC to 3.5 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility enabling it to operate with 0/+3V control and a +5V supply. A 3:8 decoder is integrated on the switch requiring only 3 control lines and a positive bias to select each path. The HMC253LC4 SP8T will replace multiple configurations of SP4T and SPDT MMIC switches.

Signal lines at the RF ports should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown above. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request. 9 - 136 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC253LC4 v00.0107 GaAs MMIC SP8T NON-REFLECTIVE SWITCH, DC - 3.5 GHz Notes: 9 SWITCHES - SMT For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com 9 - 137
